We are a different country than we were a quarter-century ago, when federal agent Jack Bauer first stayed up all night in our service. For one thing, around 90 million of us weren’t born in time for the November 2001 premiere of Fox’s 24. Another 10 million current Americans hadn’t immigrated yet, to say nothing of our countrymen who have since died or the post-2001 arrivals who have yet to officially join the team.
